TOTAL-PRINTING- MECHANISM non LISTING-MACHINES.

' Application filed September 17, 1503. Serial No.173,55 i.

. :Be it known that we, Donn E. FELT and CHARLEs P. .WETMORE, citizensofthe United States, 'residing-inChicag'o, in the county of Cook-andState of Illinois, have invented a new and useful Improvement in Total-Printing Mechanism of Listin Machines, of

whichlthe following is a spec' cation. This invention relates to thetotal printing 3o mechanism, of that class of recording arithmeticalmachines commonly known as listing or tabulating machines. structed,these machines have either been I provided witha separate operatinglever for if causing the rinting of the total, or they have been provied with a setting key whereby themechanism' isset for the printing ofthe total, so that when the mainoperating lever isnext operated,, thetotal will be recorded. In our present invention, We aim both todispense with the total printing lever and with the setting key ofprevious machines,

I and we accomplish this .result through the medium of the mainoperating lever which wenow ada t both to set or prepare the I mechanismor ,printing the total and for actuating the mechanism to the printing.In order that the operating leverinay perforrnboth these functions, inaddition to its 39 other functions, we give it a strokedifl'erent frorthe stroke which-it receives when oper- 'ating the machine in listingand adding. Thus in the case of machines whose operating levers.

.are moved toward the front of the machine inthe ordinary listing andadding operations,

We give the lever a stroke backward from its position of rest for thetotal printing, of

course, but, of course, we do not wish to be limited in this regard.During this stroke by which the total is printed and which is to bedistinguished from the return stroke of the lever in its normaloperation while listing the numbers, the lever in the first part of thestroke sets or prepares the mechanism for printing the total, and in thelast part of the stroke, it causes the printing.

In addition to this, the invention also embraces other features'ofinvention which together with the main improvement are fully ,so setforth in the description which we give below. 4 In the accompanyingdrawingforming a part of this specification, Figures 1, 2 and 3 i arepartial side elevations of portions of a listing machine embodying'ourinvention,

' Specification of Letters Patent.

As heretofore con-l Patented June 2,1908.

the operating lever beingshown only in.

broken lines'in Figs. 2 and 3 so as not to obscure the arts back of it.Fig. 4 is a plan of the mec anism shown in the other figures.

Fig. 5 is a section on the line-5-5 of Fig. 1,

and Fig. 6 is a section on the line 6-.6 of Fig. 1. l Fig. 7. is adetail elevation of the printing segmentlfor printing the-lettersS and T0pposite t e total. Fig. 8 is a side elevation of a listing machinev inwhich our improvements have been embodied. .Fig. 9 is a longitudinalsection of the same, and Fig. 10 is a section on'the line 10-10-0f Fig.8.

The present invention is shown in 8, 9 and 10, as applied to atabulatingmachine known as the com togra-ph, the construction OfWlliGhis fu ydisclosd in an cember, 1904, as- Serial No. 238,316." For thepurposes of this application, it isonly necessary to refer to a portionof the devices application filed by us on'the 27th of De- I illustratedin these figures,-and we therefore notethat 200 represents thedenominational kys, 310 one of the lon itudinal movable bar's havinginclines 340 t rough which it is actuated by the keys, the inclinesbeing adapted-to impart varying movements to the bar so that the barsare thereby enabled to determine the action of the adding and. printingmechanism. The bars 310 each actuate a corresponding variable actinglink 390',

each attached to a column actuator 400 by which the corres ondingnumeral wheel 410 is" turned in ad ing and the corresponding typesegment 39 is positioned through link 260 for printing. The link 390engages the notched graduated arm 4'50 yieldingly mounted on and rockingwith shaft 480 which we call the main actuator. The key determines whichof the notches shall be engaged by the link, and when the main actuatoris rocked forward by the lever 11 through any suitable connectin,mechanism, one const uction of which is ully disclosed in our saidapplication, No. 238,316, and of which the springs 206 Fig. 10, formapart, the link depresses the column actuator in aCCOI'dBJIGBWIth thedigital value of the key, and actuates the numeral wheel and typesegmentaccordingly. The hammers of. the printlng mechanism are shown at 1.70and swing on shaft 171. They are actuated by springs 172 and arenormally held by triggers 177 released by frames 178. The constructionof the releasing frames.

and their mode of operation are set forth in .2 7th 1900'. i

d hen the main lever moved backward as hereimifter explained, itopemtesthe lever so and causes the sliding of the cum bars 310 to a non-actingposition, through the medium of swinging lever 73 mounted on onactuating rock slmft Tl, link 83 operated by the 11min cum aud'having ashoulder engaging the lower end oi lever 73, the lever 75 on rockingshnft- 74-, and plate '76 carried by lever and engaging the projectinshoulders 95 on the cum bsrs. \Vien "the ever 36 is thus opera-ted, it-also carries with it a bar 100.

The forward movement of the r erating lever may alsoibe made a means oflif mg the tvperibhon from. its position of rest to its acting;position, and we have shown means accomplishing this result and whichare its lows: On the shaft 12 is a, czun 20 having we I points 50 21.1451, both cl' wnich. come in eonrect with e pin 21 on a lever'-'.lWJiCl9.-t 23 and connect by av link to the frame 25 pivoted 4 tadding mechai 36, and. localso be- .veen the specs operating the ribbon2?.

For printing the total, the operating"lever moved "from the position ofFig. 1, to that of Fig. As already ex )h'tined, this opera-tes tillOroe-k shaft 18, in the same manner as does the forward movement of thelever. it also causes the setting of the mechanism preparatory toprinting; the total, and this it does through the medium of a com 320 oni-z-iurl t This corn, when the lever is mowd. backward for. printing thetotal, presses against the latch. 32 which is pivoted on the elbow le er33 and is held by at stop 4-0 from swinging in one rhrection. A spring41 maintains contact by the hitch with the stop.

The lever 33- is pivoted at 34 and connected by slink {$5 with :1lever-T56 pivoted at 37. This loner has a horizontally extending arm andthrough this arm the positioning o! the type segments for miswcrprinlmgis ncrig". to its printing position shown at ms irerne carries guidesfor the ribbon or ails again to the position of Fig-.1. ,T his ribr t emain lever, and lever 36 causes the setance by arm 38 of its saidfunction. The

The lever'36 corres onds closely so far as it aids in the totalprinting, to the lever 70, of

the atent to Dorr E. Felt, No. 749,177,

' date January 12, 1904, though the patented lever is operated directlyby the handof the o erator'mstead of receiving its power from Q of themechanism for the printing of the answerand the printing thereof, inthesame way asl the-lever 70 of the patent accomplishes these results.

We have shown two ribbons in the application, the ribbon 27 being theblue or pur- 'ple commonly used in printing the numbers added andthe'ribbon 42 for the printing of the totals: The latter ribbon ispreferably red 'orsorne other color differing from that of ribbon 27., lThe backward movement of the operating. lever is intended to lift ribbon42 into acting position and it does this by the following means: Thepoint 51 of the cam 20'- jac'tuates the lever 22 and through it theribbon frame, carrying it from the position of Fig. 1 to that of Fig. 8and bringing ribbon 42 opposite the printing line, so that when theanswer is printed, it will be done in red or some othercolor.difierentfrom the ink used in listing.

,. It is frequently desirable to print what may be called sub totals,that is, totals of a portion only ofv the items listed, as, for'in-'stance, those in a particular column Instead of the rand total, and itis desirable to dihtihguisli such sub totals from the grand totals.-Forthis purpose, we add to the series 'oftype segments a special one 52having upon it the lett ers'l and'S, T being used with l the grandtotals, and S with the sub totals.

The type are arranged upon the segment as indicated at Fig. 7, the Sbeing the upper letter. The segment is mounted uponthe same shaft 26with the numeral segments and yby the user'.

, ;Adjacent to the lever 55 is a second vertical an elbow lever rockingu on shaft 61 and e l j adapted to be engaged by t e pin 31 on the.

I arm 30 of shaft 12, Then per end of lever 55'isconnected tolever 59 ylink 62 slotted 5st its unction with lever 59 and a spring 63 On theside frame of the machine is ivoted a'jlatch 56 having its forward end57 ent at ane of the hand lever. A spring 58 lever 59, the lower end ofwhich is pivoted to also connects the up er portions of the two normalposition, the pin lies atv the inner end.

of the slot, and remains there ino erative during the listingoperations, but w en the operating lever is moved for total printing,

e pin 31 rocks the elbow lever 60 to the po-' sition shown at Fig. 3 andthereby pulls.

down the forward end of the type segment 52, raising the other endsufiiciently to osi- .tion the letter Tat the printing line, an this isalways the operation when the hand lever 53is not shifted. If a subtotal is desired, the lever 53 is shifted by hand to the position ofFig. 3 and this causes the shiftin of pin ,65 from theinner to theforward end of slot 64 so that a less movement of segment 52 isprbducedthan would be the case if the in remained at the rear end of the slot.VV th the parts; in the positions just mentioned, the movement given tosegment 52 positions the letter S at the printing line.

The main lever may be arrested at its position of rest by, any suitablemechanism, such, forinstance as the spring plunger 110 entering thenotch 111 in collar 112 on the shaft of the lever. See Fig. 10.
